I have been to see several doctors, I have had pulmonary test done and everything comes back negative. My heart is in great shape, in fact the heart specialist said it was beautiful, most of the men she see at my age have high blood pressure do to smoking, drinking or high cholesterol. I have none of these issues, however I have high blood pressure or Hypertension. I do not have problem breathing all the time however it seems to connected to my sodium intake. If I do not eat any pre-prepared foods or anything from fast food I do not have too much difficulty if I prepare the food myself. My weight has been the same for eight years at 260 lb. Height 5, 11. I try to exercise when I can, I am on the go all the time, lifting and pulling pallets that weigh about 1200 lbs. each. Can you make any suggestions?
